The question will be whether or not to keep the Schiit Saga 2, which serves no functional purpose unless you have more analog sources to connect than the Wiim Ultra allows.
That said, know that if you open up a Wiim Ultra, you can easily bypass the phono preamp on the phono inputs, allowing them to be a second set of normal line-level inputs, giving you two instead of one. This bypass can easily be undone if you ever need the phono preamp back on those inputs at a later date. The FOSI V3 Monos will be a fine match for your Dynaudios. Enjoy!
